'Beast' is unfortunately a bit bland.
Idris Elba's performance is fine, I'm a big fan of his so naturally expected a bit more from him here if I'm honest - his American accent is a tad distracting, but that's probably just because I'm used to his usual dulcet tones. Sharlto Copley is solid, while young actors Iyana Halley and Leah Sava Jeffries are OK; though their characters are written to act in an irritating way.
The film could've done with a few more curveballs, most if not all that we see is pretty predictable - and even then it's all filmed and shot in a fairly 'normal' way. In short, this 2022 release didn't quite do it for me - it isn't bad, but I personally don't think it's anything good either. I'd say the beast special effect is decent, even if it was giving me more wolf vibes than lion.
The middle/end improves upon the start, though all in all it's a quintessential 6/10 flick for me.
